Abstract： This paper aims to construct a standard index system for the determining defects in non-metallic lined pressure pipelines， and analyze and summarize the principles of defect identification in this field at home and abroad. It firstly analyzes the defective characteristics of non-metallic lined pressure pipelines and their influencing factors systematically in four aspects： irrationality， degree of danger， probability of danger and revision index. By constructing this standard index system， it is expected to provide clear guidance for the defect identification of non-metallic lined pressure pipelines and enhance the safety and reliability of pipelines.

Keywords： non-metallic lining， pressure pipelines， defect identification
